PNEUMATIC CARRIER.

SPECIFICATION forming part Of Letters Patent NO. 648,37 5, dated May 1, 1900.

Application filed September 23, 1898. Renewed October 2, 1899. Serial No, 732,408. (No model.)

T0 at whom it may concern.-

Be it known that LBIRNEY O. BATCHELLER, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Pneumatic Carriers, of which the following is a true and exact description, reference being bad to the accompanying drawings, which form a part thereof. I

My invention relates to pneumatic carrier such as are used in connection with pneumatic transit-tubes, and particularly to the locking of the lid of such carriers in place, the object of my invention being to provide means for locking the lid of the carrier of a character which will by novel means provide against the insertion of a carrier into a tube in any condition except one in which the lid is securely locked in place.

The nature of my improvements will be best understood as described in connection with the drawings, in which they areillustrated, and in which- Figure 1 is a longitudinal section taken as on the line 2 2 of Fig. 2 through the lid end of a carrier and the lid itself. Fig. 2 is a cross-section on the line 1 1 of Fig. 1. Fig. 3 is a cross-sectional View taken on the line 3 3- of Fig. 2. Fig. 4 is a view showing the face of the keyway plate and keyway formed therein, and Fig. 5 is a side view of the key.

A indicates the lid end of a cylindrical carrier such as is commonly employed; B, one of the contact-rings surrounding the cylindrical body of the carrier; O, ahinge to which one edge of a lid D is secured, said lid being formed with a flange d, which closes around the end of the cylinder A and is formed, as shown, with a locking-perforation d, which when the lid is closed registers with a similar perforation a in the edge of the cylinder. On the outside and inside of the lid-plate are riveted plates E and E, the plate E having an annular groove, as indicated at a, lying inside of an inner flange, and plate E having a keyhole (2 formed in it for theadmission of a key-fiangeprojecting at one side of a keyshank. Supported in the annular groove 6 is a plate F, which by means of rivets I I is secured to an eccentric Gr, lying inside of the plate E, and to a segment-disk H, the periphcry of which is cut away at H, as clearly shown in Fig. 2. The plate F and eccentric G are formed, as shown, with a central keyway corresponding in shape to the keyway e, said keyways registering when the parts are in the position indicated in Figs. 1 and 2,

but at other times lying crosswise.

J is a yoke, which surrounds the eccentric F and has a lateral extension J, at the end of which is formed or secured a bolt K, held by means of a bracket 0 in permanent registry with the bolt-hole a.

' L is a bracket on the lid D, in which is pivoted on a pin Z a finger M M, N indicating a spring which normally throws the end M of the finger outward, the other end, M, being of course thrust inward and having a flange at its extreme end which comes in contact with the edge a of the cylinder A when the lid D is closed down upon it, the pressure exerted on this flange being in a direction opposite to that in which the spring N works,-

and the position of the parts when the lid is fully closed down being as shown in Fig. 3 of the drawings. The arm M of the finger pro jects, as shown, beyond the edge'of the segmental plate H, and when the parts are moved to withdraw the bolt K it comes opposite to the keyway portion H, and the lid being opened the spring moves the arm M up until it lies opposite to the edge of the plate and in case of the rotation of the plateH engages the plate and stops the rotation by coming in contact with one of the shoulders at the end of the keyway portion. This device, which .in itself forms a portion of the subject-matter shank I prefer to make of such length as will prevent the entry of the carrier, with the key in place, into the sending device, through which it is injected into the transmission-tube. In such a sending device, for instance,' as is shown and described in my former patent,

No. 595,75t, of December 21, 1897,. it will be quite obvious that a key projecting from' the lid of the'carrier and having any considerable length would efiectually prevent the operation of the sender. I also design to provide against the insertion of a carrier with the key. in place by providing cross-bars P extending out from the shank of the. key, which will project beyondthe edge of the carrier-cylinder,.and thus. prevent its being placed in a.

tubular'sender before the key is withdrawn.

v A very important feature of my invention key can be inserted and withdrawn when the parts are in the position indicated in. Figs. 1

andu2 but at all other times, the flange P of the key being out of registrywith the key way e, the key could neither be inserted nor Withdrawn. If already in place, it is consequently impossible to withdraw the key until the carrier has been securely locked in place,

because the key is not in registry with the keyhole until the lock has resumed this position, andbecause the lock cannot assume this position untilby closing down the lid to full locking position the finger M is moved out of engagement with the segmental plate H.

Having now described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a pneumatic carrier, a lid for closing the carrier incombination with locking'de- Vicesfor securing the lid in closed position, lock-actuating mechanism constructed as described to beoperated by a detachable key, and akeyhole and guard-plate constructed as described to prevent the entrance or withdrawal of the key to or from the lock-actuating mechanism in any position of the lock except that in which it is in looking position.

In a pneumfatic carrier,,,a lid. for closing the-carrierin combination with locking devices for securing the lid in closed position, lock-actuating mechanism constructed as described to be operated by a detachable key, a keyholeand guard-plate constructed as described to prevent the entrance orwithdrawal of the key to or from the lock-actuating mechanism in any position of the lock except that in which itis in looking position, and means, aslatch M and segment H, for preventing the .movement ofthelockingmechanismand withdrawal ofthe key when the lid is open.

In a pneumatic-carrier, a lid forv closing the carrier in combination withlocking, devices for securing the lid in closed position, lock-actuating mechanism constructed as described to be operated by a detachable key and akeyhole and guard-plate in the top of the lid constructed as described to prevent the entrance or withdrawal of the keyto or from the lock-actuating mechanism in any position of the lock except that in which it is in locking position and a key having a handle por- BIRNEY c.
